Wrap bale wet feed, method for producing the same, and apparatus for forming a lap bale in the wet feed

摘要

PROBLEM TO BE SOLVED: To provide wrap veil wet feed, and a method and apparatus that can quickly and efficiently produce the wrap veil wet feed.SOLUTION: The present invention provides wet feed comprising: compressed feed made of a feed mixture of short fragmented feedstuff, such as dry pasture and rice straw, and food processing by-products, such as brewers grain and bean curd refuse; and a wrap veil therearound comprising a spiral longitudinal winding of a plastic film, and a lateral winding of a plastic film with the full width overlying the longitudinal winding. The present invention also provides an apparatus for producing the wrap veil wet feed comprising: a spiral longitudinal winding station which forms the spiral longitudinal winding around the compressed feed such that a layer of a plastic film wound around a nozzle of an extruder partly beyond the nozzle is pulled out from the inside by the compressed feed extruded through the extrusion nozzle of the extruder; and a lateral winding station which laterally winds a plastic film with the full width around the spirally longitudinally wound compressed feed.
